This strategy could seriously backfire. Eventually Twitter could feel attacked and start thinking that Trump comments don't worth all the mess. The idea of an organisation removing the megaphone and be forced to close the Trump's account suddenly. Even a few months before the elections. Trump needs twitter's megaphone more than Twitter needs Trump.
